If you do not have FlexNet yet, you can download the free Reader installation files containing FlexNet utilities, allowing you to set up FlexNet.

You can determine the Host ID/Target ID of the machine on which the FlexNet license server is installed:

  • using lmadmin.

  • using lmhostid.

    FlexNet license server supports only one Host ID/Target ID.

To determine the Host ID/Target ID of the machine on which the FlexNet license server is installed (using lmadmin)

  1. Connect to the FlexNet License Server management Web interface.

    The default address is  http://localhost:8090 or use your server name (http://<server name>:8090).

  2. Click Administration at the top-right corner of the webpage. When prompted to sign in, enter the default administrator's credentials (admin/admin).

  3. Copy the Host ID/Target ID displayed as Ethernet Address (as in the following figure).
    Ethernet Address of the machine on which the FlexNet server is installed


To determine the Host ID/Target ID of the machine on which the FlexNet license server is installed (using lmhostid)

The lmhostid is a command line utility, which prints the Host ID/Target ID that a FlexNet license server requires on any supported system. The Lmhostid utility is available as an executable called lmutil. 

  1. Locate lmutil for a particular OS in the downloaded <product folder>\Flex_Utilities_User_Guides_Vendor_Daemons\<FlexNet version>\Server utilities folder.
  2. Run lmutil with lmhostid parameter from the command line. Lmhostid displays the default Host ID/Target ID for the current platform.


For the exact commands for a specific OS refer to: License Administration Guide (Obtaining System Hostids):

If two or more Ethernet addresses are available on the particular machine, the first one printed by the Host ID command should be used.
